1' 0 (ZZZ 107mmit may comernu' Be it known that l CLARENCE A. Bnnnnvs, a citizen of'the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in .iiydrocerhon Burners; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it nppertainstoniake and use the same.

My invention relates to hydro-carbon burners adapted for general use in furnaces, boilers, stoves and the like, and has for its object to simplify the construction and improve the operation of such devices.

Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in,

the claims.

The commercial form of this improved burner is illustrated in the accompanying drawings, wherein like characters indicate like partsthroughout the several views.

Referring to the drawings: v

Fig. l is a plulrview of theimproved burner, some parts l eing broken away;

Fig. 2 is a vertical section taken on the line 2-2 oil 1 and showing the burner set on the grate of a boiler 01 tornece.

This improved burner comprises four main elements, towit: a base member 3 of box-like form, a plate member 4. mounted as a cover for said base, s goose neck sir do livery tube 5, and a generating cone 6., The box-like base 3 has transverse, partition: 7 that divides the sameinto an air intake cherrber 8 and a dead sir chamber 9. plate 4- ispreferahly flanged so that itsets "in proper position on the top of the bon lilie base 3, and above the deed air chamber 9 it is formed with. a gcneretingbowl i0 hiving' at its axis an upstanding cone 11 that preferably rises lightly shove the rim of the bowl. The bottom surface ofihe bowl is formed with circumferentiolly and rndi" spaced upstanding combined heat-redi ting and gas-deflecting pins 12 preferably cost tepercd lugs integral withsuid bowl and cover plate. An ,oil orl'luid fuel supply pipe 13 leads upward through the co1npa.rtment"9 and is tapped into the cone 11. The upper .endof this pipe 13 communicates with. a sine oil deliverypipccr pipe section i l! nestis threaded into the top of the cone ill The cover and projects above the same to allord a contracted oil delivery nozzle.

The gene-rating cone 6 is a hollow structure, into the apex of which is screwed the threaded upper portion of the pipe section 14, thereby supporting the generating cone 6 free for vertical adjustments in respect to the bowl H) and with the inner surface of said generating cone exposed to the hot gases rounds the generating cone 6 and terminates shove the top'or rim of the bowl 10. To detochahly hold'the sir tube 5 in. the position just stated, it is provided at its receiving end with an outstanding flange 15 having notches through which screws 'lGerc pussct and screwed into the cover plate 4.

I ln spplying the lmrner above described to the grate of a boiler, heater or furnace, the upper end of the boxdilre base 3 is placed directly on the base 3 and all portions of the grate outward of the base are closed against the passage of air therethrough by suitable means, such as bricks y or the like.

For safety, the bowl 10, below its rim and at one side, is provided with an overflow port 17 from which an oil discharge pipe 18 leads toe suitable point of discharge. For controlling the supply of fluid fuel to the burner and for cutting the supply of fluid'ziuel ed in case the flame should go out, there should he an overflow of oil into the bowl 10, and valve mechanism in connection, such as disclosed in my pending application Serial No. 508,069. iled October 17, 1921, and allowed July 19, 1922, may be em loyed, but such connection need not here be 'urthpr considered.

Upemtion. The operation of the burner described will be substantially as follows:

This burner Will burn almost any kind of fluid fuel, but is intended especially for the lower gredehydro earhons, such as fuel oil, distillate or low grade kerosene; The

' reaches fiuid fuel delivcred through the pipes 1.314 will overflow at the apex oi? the generating cone 6 and will trickle downward over the external steps or annular shoulders ot'suid cone until it is vaporized, and when the burner is hot, the m mrizution will be very rapid and will be complete before the fuel the bottom of the generating cone. The air drawn in by natural drought or otherwise through the chamber 5 sud-nix tube 5 Will be delivered downward around the generating cone and into the bowl and through the spaces between the pinslQ. When the burner is in action, the pins 12 will be kept very hot so that they readily assist in maintaining the combustion and making the combustion. complete. In fact, the scidpins not not only heat" radiators but as deflectors to break up the stream of comminglcd air and hydrocarbon vapor or the flames resulting therefrom as they are drawn downward, outward and upward through or over the bowl 10. Thus, tic most complete combustion is insured. The taper of the tube 5 to "8N1 its delivery end produces the most rapid travel of the air at the point or delivery against the hydrocarbon vapors and further intensifies the combustion. By vertical adjustments of the generating cone 6, it may beset in respect to the delivery end of the air tube so as to give the most eiiicient flame. When the flame is low, it will come into direct contact only with the upper ends of the pins 12, but when the flame is its greatest intensity, it will completely embrace the-said pins and be dashed against the bottom of the bowl. Even when the flame is low, however, the numerous pins will be kept hot enough to centre ly above feature, for i s-eliminates the necessity of the, independent pilot light and makes it possible to graduate the Home to without resorting to the intermittently lighting main flame. Moreover, t

of very simple construction and low cost while, at the some time, elficient.

What i claim is:

the heat required usual expedient of case the finine should andturning off the e burner describenl 1. A burner ofthe kind described comprising a bowl having on its bottom aplurnlity of laterally spaced upstanding combined heat-radiating and gasdeflecting pins;

or pro ections,
